C-Series Solar Charge Controller - 12 AmpsPV charge, lighting and load controllerThe C12 charge, lighting, or load controller is uniquely sophisticated. As a charge controller, it features three-stage charging, user definable voltage parameters, and automatic equalization.Standard in the C12’s load control circuitry are field adjustable low voltage disconnect and reconnect points, along with a five minute low battery disconnect signal. The C12 also functions as a lighting controller.Lighting run time is adjustable from two to eight hours or can be set from dusk to dawn operation. It is used worldwide in a variety of applications, including remote village lighting systems and automatic outdoor lighting. An optional battery temperature sensor manages battery charging based on battery temperature.Features:Improve battery life with pulse width modulated (PWM) multi-stage temperature compensated chargingTwo-year standard warrantyPV charge and load controllerAutomatic lighting controllerElectronic detection of short-circuit, overload, over-temperature and reverse polarity conditionsTolerance to hostile environments with conformal-coated boards and powder-coated enclosureField adjustable voltage and battery set pointAutomatically disconnects from the battery at nightCompatible with negative ground and ungrounded systemsWARNING: This product can expose you to chemicals including Diisononyl Phthalate (DINP) which is known to the State of California to cause cancer, and Di-isodecyl Phthalate (DIDP) which is known to the State of California to cause reproductive harm.
